[public-dns-discuss] Re: SERVFAIL when looking up matrix.org on 8.8.8.8 and 8.8.4.4



thanks. yup, it resolved itself after about 45 minutes; will diagnose via dns.google.com in future. It could be good to add this to https://developers.google.com/speed/public-dns/docs/troubleshooting for future generations :)

It is possible there was a routing issue between Google and Cloudflare; this would cause inability to resolve names  for your domains even while your ISP had connectivity to both Google and Cloudflare.

If you have these sorts of problems in the future, try to use dns.google.com to resolve the domain, for example https://dns.google.com/query?name=matrix.org and if there are problems with the authoritative servers, there is often a diagnostic comment that provides more helpful information than the simple SERVFAIL error message you might get with dig.

At any rate, I'm not seeing any problems with those domains right now.
